. APPARATUS FOR EXTRACTING OIL FROM OLEAGINOUS SEEDS, do.

SPECIFICATION forming part of Letters Patent No. 270,291, dated January9, 1883.

Application filed November 25, 1882. (N 0 model.)

This invention relates to that class of appa ratns which is employed forthe extraction of oil from oleaginous seeds, and is designed to improvethe construction of the heater or kettle in which the ground seed ormeal is cooked preparatory'to placing it in the press for the expressionof its oil.

My invention consists in a kettle divided into hollow compartments,combined with slidedoors for closing the spaces between the compartmentsand forming continuations of the walls of the latter. a

The invention also consists in a kettle di- Y vided into two or morecompartments having their walls jacketed with wood, paper, or othermaterial, so as to create an airspace around the compartments.

The invention also consists in the combination, with the communicatingcompartments having steam or hot-air spacesin their bottoms, ofslide-doors for closing the passages between said compartments.

Theinvention embraces other features, all

of which will be fully hereinafter explained in detail.

In the accompanying drawings, illustrating my invention, Figure I is apart vertical section and part elevation of the apparatus, the

upper portion and the heater being shown in section. In this figure thesectional covers or sides for the spaces between the several divisionsor compartments are all detached but one. The front standard is also notshown in this figure. Fig.1I is a top or plan view with a part shown inhorizontal section. Fig. III is a top edge view of one of the detachableside covers for the spaces between the compartments. Fig. 1V is a sideview of the said cover. Fig. V is a sectional detail of a slidingtrap-door, which is adapted to be opened so as to allow-the passage ofmeal from one compartment to the other. Fig. VI is a plan view of oneofthe sliding trap-doors.

My improved heater consists of a cylindrical shell or case, which isdivided into two or more chambers or compartments by means of horizontalpartitions, in which latter steam is introduced, so as to heat thematerial contained in the compartments. In order to allow access to behad to any one of the compartments, the shell is composed of'a series ofannular walls secured to vertical standards, and detachable 6o doors orsides which are located between the fixed annular side walls. In effectthe fixed walls constitute the sides of receptacles for containing theseed, and the removable walls or sides constitute doors for the spacesbe- 6 tween the top of one receptacle and the bottom of the next upperreceptacle, whereby the kettle composed of the fixed and detachablesides contains all of the compartments.

A A refer to the compartments of the cylindrical kettle, the walls andbottoms ofwhich said compartments are supported by standards A. Thesecompartments communicate with each other through openings B, formed inthe horizontal partitions O, which constitute their bottoms, whereby themeal from one compartmentcan be passed into the nextlower compartment.Sliding doors D are provided for opening or closing thepassages throughthe bottoms of the compartments, each door being formed with two or moreopenings, 1), which can be brought to register with the openings in thepartitions G, constituting the bottoms of the compartments, saidopenings being arranged in a line radiating from the center of thecompartment, so that the door composed of an oblong plate can he slidthrough an opening at the side of the compartment and moved over thepassages B, so as to open or close the same. The wall of eachcompartment consists of an inncrjmetal band or cylinder, E, one of whichis shown in Fig. 1. These metal walls are seated upon the bottoms of thecompartments in which they are located, and are each provided on itsouter side with marginal 5 ribs, to which is fastened a band, F, ofwood, paper, or other material, so as to form an annular air-space, F.The construction and material of these jackets can be varied, and can besecured by metal hoops or in any other 10o convenient way. The standardsfit against the outer sides of thejaokets F, which constltute the fixedportions of the walls of the kettle, and are secured by bolts or othersuitable means to the metal bands or rings E. The bottoms O of thecompartments are chambered, as indicated at c; and tosuch end saidportions can each be composedot' an inner and outer ring, with metalplates secured to their upper and lower sides, provided with centralbearings for a vertical shalt, Gr, upon which the agitators Garemounted. The spaces between the compartments are closed by sectionaldetach able sides orjackets H, one or all of which can be removed toadmit of the contents of the compartments being inspected. Thesedetachable sides are preferably adapted to slide in grooves formed inthe standards, although, if desired, they can be hinged to the standardslike ordinary doors; or the sides or cover for each space can be made inone piece. By such arrangement the walls of the compartments and thesides H constitute in effect a single cylindrical casing, divided by aseries of partitions into communicating compartments, whereby the heatradiated from'thebottom of one compartment will be utilized in warmingthe contents of the next lower compartment. H indicates a sliding doorfor discharging the meal from the lowest compartments, and I denotesgear-vs heels for operating the shaft carrying the agitators. Theseagitators in revolving around the shalt stir the meal, and also sweepthe same over the opening in the bottom of the compartments. Theconstruction of the door D can be varied, that shown, however, beingboth simple and convenient.

K, Figs. 2 and 5, is a metal plate, provided with openings registeringwith the openings in bottom G, and secured by rivets 0 between the twotop and bottom portions of the said bottoms O. The door D, as shown inFig. 5 and dotted lines Fig. 2, slides under said plate and is supportedby cleats L, secured to the bottom 0.

In using this apparatus raw meal is admitted into the upper compartmentby suitable means-such, for example, as a spout which will discharge themeal in a continuous stream into said compartment, in which the meal isthen heated. The meal can then be emptied into the next lowercompartment by opening the passages between the two, in which lowercompartment the heatin g and tempering process is continued for acertain length of time, after which the meal can be emptied into thenext lower compartment, and finally carried off to charge the press. Asno fresh meal willhave been added to the charge after leaving the firstcompartment, the meal will be thoroughly and equally tempered. Steam isadmitted intothe chambered bottoms or partitions through openings M, anddischarged through openings M by means of any suitable pipe-connection.

A kettle for extracting oil has heretofore been. provided with ajacketand a'hollow bottom to form a steam-space, said kettle containing arevolving stirrer, and having its bottom provided with an openingcontrolled by a pivoted gate, so that the material treated in the kettlecan be discharged into a similarly-constructed kettle located beneaththe same.

Such, however, is not my invention.

Having thus described my invention, what I claim is 1. In a heater forpreparing meal from oleaginous seeds for the extraction of oil, a kettledivided into compartments, substantially as described, with theslide-doors D for closing the spaces between the compartments andforming continuations of the walls of the latter, as set forth.

2. In an apparatus for preparing meal from oleaginous seeds for theextraction of oil, a kettle divided into two or more compartments havingtheir walls jacketed with wood, paper, or other material, so --as toleave air-spaces around the compartments, for the purpose set forth.

3. In an apparatus for preparing meal from oleaginous seeds forextracting oil, the combination of the walls E F and removable sides Hwith the horizontal partitions having valved openings, substantially asdescribed.

4. The combination, with the herein -described communicatingcompartments having steam or hot-air spaces in their bottoms, of theslide-doors for closing the passages between said compartments, and therotary agitators, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
